Med-X back and neck therapy studies.
Orthopedics, October 1995. The Clinical Effects of Intensive Specific
Exercise on Chronic Low Back Pain: A Controlled Study of 895 Consecutive
Patients With 1-Year Follow Up. This study reports that of the 895 patients,
76% had good or excellent results. Patients with either radicular or referred
leg pain responded just as well as patients with isolated low back pain.
Prior to this study, these patients had seen an average of three physicians
and had failed six different treatment options, including chiropractic,
epidural injections, facet injections, ultrasound, traction, medication,
and electrical stimulation. Patients completing the program had dramatically
less (67%) medical re-utilization in the year after than a comparable
control group. Click

Can Spinal Surgery be Prevented by Aggressive Strengthening Exercise?
A Prospective Study of Cervical and Lumbar Patients. Forty-six of sixty
participants completed the program. At an average of sixteen months after
completion, only three required surgery after completing the program.
In other words, patients who were informed they required back or neck
surgery had a 92% chance of avoiding surgery with aggressive spinal strengthening
on the Med-X Medical Machines. Click

Spine, November 1999. Restorative Exercise for Clinical Low Back
Pain A combined study between Physicians Neck and Back Clinic and the
University of California at San Diego included data on 400 individuals
with chronic back pain. Patients were evaluated at initiation of treatment,
at discharge, and 1 year after discharge. Health care re-utilization was
dramatically lowered at both clinics to almost identical levels, thus
validating the results of each. In the year after completion of treatment,
only 12% of patients needed to re-enter the health care system for spinal
problems. Click

The American Journal of Sports Medicine, Number 6, 1991. Quantitative
Assessment and Training of Isometric Cervical Extension Strength. Because
the cervical muscles must support the weight of the head, head and neck
pain often originate as a result of muscular weakness. Although strengthening
the neck may help prevent pain and injury, effective training programs
for the cervical muscles have not been established. Accurate assessment
of cervical extension strength requires stabilization of the torso to
isolate the cervical extensor muscles and minimize the contribution from
the torso and upper extremities, measurement through a full range of motion,
correction for the influence of head weight during testing, and standardization
of the testing position and procedures. The study showed that repeated
measures of isometric cervical extension strength are highly reliable
and can be used for the quantification of isometric cervical extension
strength through a 126 degree range of motion. It also showed that training
the cervical extensors 1 day per week can significantly increase isometric
cervical extension strength through most of the range of motion. Click

Medicine and Science in Sports and Exercise, Vol. 31, 1999. Low
Back Strengthening for the Prevention and Treatment of Low Back Pain.
Study relates how isolated lumbar extension exercise with the pelvis stabilized
using specialized equipment elicits the most favorable improvements in
low back strength muscle cross-sectional area and vertebral bone mineral
density. Improvements occurred independent of diagnosis, are long-lasting,
and appear to result in less re-utilization of the health care system
than other more passive treatments. Click

Spine, Number 68, 1992. Changes in Isometric Strength and Range
of Motion of the Isolated Cervical Spine After Eight Weeks of Clinical
Rehabilitation. This study was one of the first to objectively measure
changes in strength and range of motion in patients with non-spinal cord
injuries of the cervical spine. Significant gains were seen in strength
as well as range of motion and perceived pain was significantly reduced.
This study showed that testing and training of the isolated cervical spine
is a safe and viable method of clinical assessment and treatment of a
varity of cervical spine disorders. Click

The American Journal of Sports Medicine, Number 5, 1989. Effects
of Resistance Training on Lumbar Extension Strength. This study demonstrates
that healthy normal individuals show a significant increase in lumbar
extension strength when these muscles are effectively isolated and trained.
The magnitude of strength gained over the 10 week period is much greater
than strength increases found with the average muscle group within the
same period, and indicates that the lumbar extensor muscles were in a
deconditioned state prior to training. In addition, 10 of the 15 subjects
that trained had reported using the Nautilus low back machine on a regular
basis prior to the study period. This supports the concept that commercially-available
"low back" machines do not isolate the lumbar muscles and that the lumbar
extensor muscles must be effectively isolated through pelvic stabilization
in order to elicit a training response from progressive resistance exercise.

Pelvic Stabilization During Resistance Training: Its Effect on the Development
of Lumbar Extension Strength. Study shows how the "No stabilization" and
the "stabilization" groups showed significant and similar increases in
the weight load for training. However, the post-training isometric torque
values describing isolated lumbar extension strength improved only for
the "stabilization" group. Therefore, pelvic stabilization is required
to effectively train the lumbar extensor muscles. The increased load for
the "no stabilization" group is attributed to increases in strength of
the hamstring and buttock muscles. Click
